Command Summary

MOTOROLA DSP SIMULATOR REFERENCE MANUAL 2-35

2.3.21 OUTPUT: Assign Output File

OUTPUT [#n] [T] addr/port/periph/pin[_group] TERM/file [ioradix/-RS] [-A/-O/-C]

OUTPUT [#n] [T] addr/port/periph/pin[_group] OFF

OUTPUT [#n] [T] history TERM/file/OFF [-A/-O/-C]

OUTPUT [#n] [T] ehistory TERM/file/OFF [-A/-O/-C]

The output command stores data from a peripheral, memory location, or device pin to the

specified destination. The valid peripheral and port names for the selected device can be

obtained by using the Simulator’s "help periph" and "help port" commands.

The output destination may be a disk file or the user’s terminal. Use of the keyword

TERM assigns output to the terminal. The Simulator can store data only or time-data

pairs. Use of the keycharacter T specifies the time-data pair format. The output data is in

ascii. The data value may be expressed in hexadecimal, decimal, or floating point for

memory and peripheral name assignments, in pin data form (0,1,H,L,n,p,X) for assign-

ment to individual digital pins, or as single precision floating point for assignment to indi-

vidual analog pins with the -RF radix designator.

The output radix for the data value is specified using -RD, -RF,-RH,-RU or -RS following

the filename. The -RF radix, when specified for a single output pin, will output the analog

single precision floating point value associated with the pins analog function. The -RS ra-

dix is valid only for output memory locations. It interprets values written to the specified

memory location to be the address of a null terminated character string in the same mem-

ory space. The character string will be displayed or written to an output file. This string

radix is provided primarily for use when debugging programs created with the C Compiler.

The output time value is always expressed in decimal. Chapter 3 contains a thorough de-

scription of the output file format. A keycharacter -A, -O, or -C may be specified to select

append, overwrite, or cancel if the filename already exists. As a default, the user will be

prompted during command execution.

Assignment to a memory address causes all subsequent writes of that memory address

to store data in the output file.

If a filename suffix is not specified, the Simulator will attach ".io" to a non-timed output file

and ".tio" to a timed output file.

The third form of the output command creates a continuous log of the device execution

addresses and disassembled opcodes. The output format is similar to the output gener-

ated by the Simulator history command.

The fourth form of the command, which specifies ehistory, is an extended version of the

output history command. Additional execution history information is logged to the output

file, including device wait state cycles and bus arbitration cycles and indication of other

stall conditions. The extra information is preceded by double asterisks in the log file. Only

one of output history or output ehistory may be active.
